In a large pot, bring salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside.
In a bowl, toss the shrimp with Cajun seasoning until evenly coated.
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the seasoned shrimp and cook for about 2-3 minutes per side, or until they are pink and opaque. Remove the shrimp from the skillet and set aside.
In the same skillet, add the remaining tablespoon of olive oil. Sauté the minced garlic for about 30 seconds until fragrant.
Pour in the heavy cream and bring to a gentle simmer. Gradually whisk in the Parmesan cheese until melted and the sauce is creamy. Season with salt and pepper to taste.
Add the cooked fettuccine and sautéed shrimp into the sauce, tossing gently until everything is well combined and coated with the Alfredo sauce.
Plate the Cajun Shrimp Alfredo and garnish with chopped fresh parsley for a pop of color.
